CHIMNEY PIPE
The FMI PRODUCTS, LLC chimney system
consists of 12", 18", 24", 36" and 48" snap-
lock, double-wall pipe segments, planned
for maximum adaptability to individual site
requirements. Actual lengths gained after t-
ting overlaps must be taken into consideration
(lineal gain) and are given in the lineal gain
chart (see Figure 6). Lineal gain is the actual
measurable length of a part after two or more
parts are connected. For Canada, use chimney
parts designated "HT".
A SSEMBLY AND INSTALLATION OF
DOUBLE WALL CHIMNEY SYSTEM
Each double wall chimney section consists
of a galvanized outer pipe, a stainless steel
inner ue pipe and a wire spacer. The pipe
sections must be assembled independently
as the chimney is installed.
When connecting chimney directly to the
replace, the inner ue pipe section must
be installed rst with the lanced side up.
The outer pipe section can then be installed
over the ue pipe section with the hemmed
end up. Press down on each pipe section
until the lances securely engage the hem
on the replace starter. The wire will assure
the proper spacing between the inner and
outer pipe sections. Continue to assemble
chimney sections as outlined, making sure
that both the inner and outer pipe sections are
locked together. When installing double wall
snap-lock chimney together, it is important to
assure the joint between the chimney sections
is locked. Check by pulling chimney upward
after locking. The chimney will not come apart
if properly locked. It is not necessary to add
screws to keep the chimney together (excep-
tion - see Figure 9, page 9).
